Kafka Won’t Save Your Architecture If You Don’t Understand Coupling

Here’s what Kafka changes, what it hides, and why “async” can still fail hard. Check more stories related to programming at: https://hackernoon.com/c/programming.

Many teams treat Kafka, RabbitMQ, or SQS as automatic solutions for decoupling and resilience. In reality, queues only reduce certain kinds of coupling while introducing new ones: hidden dependencies, ordering assumptions, retry semantics, duplicate delivery, stale events, and shared infrastructure risk. They also make failures harder to observe. Message queues are powerful tools, but they do not eliminate complexity — they move it.
